How to Make the Dock Appear Instantly When Dock Hiding Is Turned On

macOS hides the Dock smoothly by default, but this animation introduces a short delay every time you hover to reveal it. If you prefer an instant response, you can remove both the hover delay and the slide-in animation using Terminal.

The Problem

The Dock has two built-in slowdowns:

• Hover delay — a short pause before it starts showing.
• Animation time — the duration of the slide-in motion.

Both can be disabled.

The Fix

Open Terminal and run:

defaults write com.apple.dock autohide-delay -float 0
defaults write com.apple.dock autohide-time-modifier -float 0
killall Dock
